Ingredients:
- 1 ½ cups (180g) Graham Cracker Crumbs
- ¼ cup (50g) Granulated Sugar (for crust)
- 6 tablespoons (85g) Unsalted Butter, melted
- 16 oz (450g) Full-Fat Cream Cheese, softened
- 1 cup (200g) Granulated Sugar (for filling)
- 1 teaspoon Vanilla Extract
- Zest of 1 small Lemon (optional)
- 1 cup (240ml) Heavy Whipping Cream, cold
- 1 cup (200g) Granulated Sugar (for topping syrup)
- ½ cup (120ml) Water (for topping syrup)
- 2 teaspoons Unflavored Gelatin Powder
- ¼ cup (60ml) Cold Water (for blooming gelatin)
- Pinch of Salt
- 1 teaspoon Vanilla Extract (for topping)
Instructions:
- Prepare the Crust: Combine graham cracker crumbs, ¼ cup sugar, and melted butter. Press firmly into the bottom and slightly up the sides of a prepared 9-inch springform pan. Chill while preparing the filling.
- Bloom the Gelatin: Sprinkle gelatin powder over ¼ cup cold water in a small bowl and allow it to sit (bloom) for 5 minutes.
- Make the Syrup: Combine 1 cup sugar and ½ cup water in a saucepan. Heat without stirring until the sugar dissolves. Insert a candy thermometer and cook the syrup to 240°F (Soft-Ball Stage).
- Dissolve Gelatin: Once the syrup hits 240°F, immediately remove from heat. Whisk in the bloomed gelatin mixture until fully dissolved. Set aside to cool slightly until it is warm, not hot.
- Prepare the Filling Base: Beat the softened cream cheese, 1 cup sugar, and lemon zest until perfectly smooth and lump-free. Slowly beat in the cooled gelatin/syrup mixture until fully incorporated.
- Fold in Cream: In a separate, cold bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until just combined, being careful not to deflate the air.
- Assemble & Chill: Pour the filling over the chilled crust. Smooth the top and chill in the refrigerator for a minimum of 6 hours, or ideally overnight, until completely firm.
- Make the Marshmallow Whip: When the cheesecake is set, combine the remaining ½ cup sugar and ½ cup water in a clean saucepan and cook to exactly 240°F (Soft-Ball Stage).
- Whip the Topping: With the electric mixer running on medium speed (using a whisk attachment), slowly stream the hot syrup into the mixer bowl. Add the vanilla extract. Beat on high speed for 10-15 minutes until the mixture is brilliantly white, thick, glossy, and the outside of the bowl is cool to the touch.
- Top and Serve: Pile or pipe the marshmallow whip onto the chilled cheesecake. Use a kitchen torch to lightly toast the peaks for extra flavor, if desired. Chill briefly again before slicing.
